Aleister & Amanitas by Phillip Newman.

The English occultist Aleister Crowley was notorious for his penned practical pranks. From discussing sex magick in terms of diabolical child sacrifice to potentially discussing psychedelic drug use under the cloak of sex magick, Crowley was a master of the art of obscurum per obscurius; of “explaining the obscure by means of the more obscure.” While we know from his diaries that he certainly was wont to engage in magick of the sexual variety, it is our suspicion that, in at least some instances, when Crowley was outwardly explaining sex magick in his books, he may well have actually been discussing the occult use of Amanita muscaria mushrooms. The same would be in perfect keeping with his modus operandi, i.e., obscurum per obscurius.
